<u>Answer:</u> The percentage abundance of isotope is 69 %.
<u>Explanation:</u>
Average atomic mass of an element is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.
Formula used to calculate average atomic mass follows:
.....(1)
We are given:
Let the fractional abundance of isotope be 'x'
- <u>For isotope:</u>
Mass of isotope = 62.93 amu
Fractional abundance of isotope = x
- <u>For isotope:</u>
Mass of isotope = 64.93 amu
Fractional abundance of isotope = (1-x)
- Average atomic mass of copper = 63.55 amu
Putting values in above equation, we get:
Converting this fractional abundance into percentage abundance by multiplying it by 100, we get:
Hence, the percentage abundance of isotope is 69 %.
Answer:
λ = 521nm
Explanation:
To convert wavelength to frequency we need to use the equation:
ν = c / λ
<em>Where ν is frequency: 5.76x10¹⁴s⁻¹;</em>
<em>c is speed of light: 3x10⁸ms⁻¹; </em>
<em>And λ is wavelength in m:</em>
Wavelength is:
λ = c / ν
λ = 3x10⁸ms⁻¹ / <em>5.76x10¹⁴s⁻¹</em>
λ = 5.21x10⁻⁷m
= 521nm
Answer:
This process, which is the opposite of vaporization, is called condensation. As a gas condenses to a liquid, it releases the thermal energy it absorbed to become a gas. During this process, the temperature of the substance does not change. The decrease in energy changes the arrangement of particles.
